Maxillary first premolar root canal

What is the treatment for an infected root canal? What are the signs of a root canal infection? Should I get a root canal or pull the tooth?

Although it usually has two canals , it may rarely have three and this third canal can easily be missed. Cams and Skidmore reported that the incidence of maxillary first premolars with three roots , three canals , and three foramina was of the cases studied. The root is considerably shorter than in the canine, and distal curvature is not uncommon.

If the mesiodistal distance distance is equal to or wider in the root than the crown, expect three roots. The number of canals each first premolar have – have canals , have canal, and have canals. Type IV, are Type II, are Type I. Approximately to of maxillary first premolars have canals , while to have just canal.

Three-rooted maxillary first premolars are uncommon, with an incidence of 0. Mandibular second premolars have been shown to have root canal at the apex in 97. The majority of maxillary first premolars had root (4 ) or roots (5 ). Regardless of the number of roots , the vast majority (8 ) had root canals , with type IV (2-2) being the most common canal configuration (6 ). Numerous studies using the clearing method showed a higher incidence of this anatomic variation, ranging from 1.

As with the first maxillary premolar, the apical third of the root may curve quite considerably, mainly to the distal, sometimes buccally. The access cavity is similar to the first premolar. The video depicts access opening on a maxillary premolar. The location of the orifices can be seen in the video.

Clinical management involving maxillary first premolar tooth with unpredictable root and canal morphology may pose some challenges. Usually those problems tend to be related to number of roots and canals but rarely tooth length. The first maxillary premolar may have or more canals in which any of the canals could be missed during treatment. The maxillary first premolar is one of two teeth located in the upper jaw, laterally (away from the midline of the face) from both the maxillary canines of the mouth but mesial (toward the midline of the face) from both maxillary second premolars. Maxillary first premolar with three root canals: a case report.

This tooth initially had three distinct canals in the mesial buccal root. Following final shaping, two canals joined at various levels, but the third canal had no connection. Carlos Franco (ISCSEM. UIC) Special thanks to Diogo Guerreiro and Mário Martins. For example, diameter root canal orifice of maxillary first premolars is larger in 20s than that in 40s , and the widest root canals of maxillary central teeth were in the 15–year age group.

The data of maxillary first premolars presented here may provide the appearance and internal structure of human maxillary first premolars in adolescents.

A possible variation of maxillary first premolar with three roots and three independent root canals is the pres-ence of a common buccal orifice, which subsequently splits into two separate canals (see Figure a, b). This format was described in maxillary first premolars with a frequency of 2. The distribution of root canal shapes in the sample showed that all teeth with two or three roots had type I root canals (each canal had one apical foramen). Conversely, most of the single-rooted maxillary first premolars had root canal shape type II (two canals converging in the same apical foramen).

The most common canal configuration for the maxillary first premolar is two separate canals in one root (Vertucci type IV) with a frequency of about 60–. One canal that extends from the pulp chamber and dividing in the mid-root into two canals (Vertucci type V) can occur in 6– of cases. MOD pin retained amalgam MOD composite resin.

It has four lobes (three buccal -the middle is well developed (the buccal cusp)- and one lingual (the lingual cusp).
